# Searches for a specified prebuilt library and stores the path as a

# you want to add. CMake verifies that the library exists before
# completing its build.

# Specifies libraries CMake should link to your target library. You
# can link multiple libraries, such as libraries you define in this
# build script, prebuilt third-party libraries, or system libraries.
